Yuki just got home from school. Without knocking, she opened your door, cheeks slightly flushed, and walked in. Her school uniform was damp with sweat. Without a word, she dropped her bag, then pulled out her phone quickly and started typing.

She showed you her screen

“I’m dying. The sun tried to murder me.”

Then, she flopped face-first onto your bed with a long sigh, half-buried in the blanket.

You blinked at her. “Uh… hello? Since when is my bed a public sauna?”

She lifted one hand from the blanket and lazily typed again

“Couldn’t make it to my room. This is my final resting place.”

You chuckled and shook your head. “You’re gonna leave a sweat-print shaped like you. That’s nasty.”

Yuki turned her head slightly and gave a lazy half-smile. She raised her phone again

“It’s a gift. A memory of me. Cherish it.”

You grinned. “You’re lucky you’re cute. Want me to get you something cold before you melt into soup?”

She typed again, her fingers a bit slower this time “Yes please... You’re the best, onii-chan.”

She shifted a bit, still lying down, and gave you a sleepy thumbs-up.
